* Change packed struct layout so that field sizesDuncan Sands2008-06-045-23/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are the same as in unpacked structs, only field positions differ. This only matters for structs containing x86 long double or an apint; it may cause backwards compatibility problems if someone has bitcode containing a packed struct with a field of one of those types. The issue is that only 10 bytes are needed to hold an x86 long double: the store size is 10 bytes, but the ABI size is 12 or 16 bytes (linux/ darwin) which comes from rounding the store size up by the alignment. Because it seemed silly not to pack an x86 long double into 10 bytes in a packed struct, this is what was done. I now think this was a mistake. Reserving the ABI size for an x86 long double field even in a packed struct makes things more uniform: the ABI size is now always used when reserving space for a type. This means that developers are less likely to make mistakes. It also makes life easier for the CBE which otherwise could not represent all LLVM packed structs (PR2402). Front-end people might need to adjust the way they create LLVM structs - see following change to llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51928 91177308-0d34-0410-b5e6-96231b3b80d8
